Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery for corn planting, and specifically relates to a hand-push corn planter. Background Technology

[0002] With the improvement of planting and cultivation techniques and the popularization of agricultural mechanization, many crops are now grown mechanically, saving manpower and resources and improving production efficiency. Corn is a major grain crop in my country, widely distributed and with a large planting area. Sowing is a crucial step in production, and the level of sowing technology directly affects yield. Currently, traditional seeders are large and inconvenient to move when sowing corn in small areas, reducing sowing efficiency.

[0003] Therefore, there is a miniaturized seeding device in the prior art that can solve the problems of traditional equipment being large in size and difficult to operate. For example, patent application number CN213127071U discloses a portable corn planter. This device, while ensuring small size and integration, uses a motor to drive a flap to cultivate the land, and at the same time, a fourth control switch works with a rectangular frame to sow seeds in a conical bucket.

[0004] However, when using this equipment, the operator needs to stop pushing the machine at the planting site to wait for it to clear the land before sowing, and then move to the next planting site to repeat the process. Therefore, using this equipment is inefficient and cannot simultaneously perform multiple functions such as clearing, quantitative sowing, and fixed-distance sowing, which significantly reduces the operator's efficiency.

[0038] like Figures 1-9 As shown, a hand-push corn planter includes:

[0039] A support 1 is provided with a pusher 11 at its upper end. The support 1 is provided with a discharge cylinder 12, a motor 13 and a wheel set 14.

[0040] The feeding box 2 has its opening end fixedly connected to the bracket 1. The bottom of the feeding box 2 is provided with a discharge pipe 21, which is connected to the discharge cylinder 12.

[0041] A trencher 121 is fixedly installed at the lower end of the discharge cylinder 12;

[0042] The support 1 is provided with a piston connecting rod mechanism 15, and a discharge rod 5 is slidably provided in the discharge cylinder 12. The upper end of the discharge rod 5 is rotatably connected to the piston connecting rod mechanism 15. A storage trough 51 is provided on the discharge rod 5 at the position facing the opening of the discharge cylinder 12. The volume of the storage trough 51 is set to be able to hold one or two corn kernels.

[0043] The piston connecting rod mechanism 15 is connected to the motor 13 for transmission, so as to switch the communication state between the discharge cylinder 12 and the storage tank 51 during the reciprocating motion of the discharge rod 5, so as to send out the corn in the storage tank 51, and to sow at a fixed distance through the reciprocating motion gap of the discharge rod 5.

[0044] Working principle:

[0045] When the operator needs to plant corn using this device, the corn kernels must first be put into the feeding box 2, and the motor 13 located on the support 1 must be started. The pusher 11 is then pushed to drive the wheel set 14 on the device forward. The device drives the furrow opener 121 to open up the soil in front. During the forward movement, the motor 13 (driven by the battery box 6 mounted on the bracket 1, which contains a battery, such as a commercially available lead-acid battery or lithium battery) drives the piston-linking mechanism 15 to rotate. At the same time, the piston-linking mechanism 15 drives the discharge rod 5 to reciprocate within the discharge cylinder 12. At this time, corn kernels can flow into the discharge cylinder 12 through the discharge pipe 21. When the continuously extending and retracting discharge rod 5 slides down to face the opening of the discharge pipe 21, one or two corn kernels will flow into the storage trough 51. Then, when the discharge rod 5 slides down to extend beyond the lower end of the discharge cylinder 12, the corn kernels flow out from the storage trough 51 into the furrow opened by the furrow opener 121, thus achieving the purpose of sowing corn kernels. Subsequently, under the action of the piston connecting rod mechanism 15, it reciprocates. When the empty storage trough 51 rises to face the discharge pipe 21, a small amount of one or two corn kernels slide back into the storage trough 51. Then, the discharge rod 5 rises and then falls to extend to the bottom of the discharge cylinder 12, and then slides into the furrow opened by the furrow opener 121. In this way, while opening up the land, the reciprocating motion achieves the fixed distance and quantity of corn planting.

[0046] In the above technical solution, the piston connecting rod mechanism 15 includes a connecting rod 151 and a set of symmetrical cranks 152, wherein:

[0047] One end of the connecting rod 151 is rotatably connected to two cranks 152 via a bearing and a rotating shaft I, and the cranks 152 are symmetrically arranged on both sides of the rotating shaft I;

[0048] Furthermore, one end of the connecting rod 151 is rotatably connected to the U-shaped connecting end 52 via a bearing and a rotating shaft II, and the U-shaped connecting end 52 is connected to the upper end of the discharge rod 5;

[0049] Each crank 152 has a fixed shaft 152-A located at the center of its outer side, and one of the fixed shafts 152-A is connected to the motor 13 via a transmission wheel 152-AA.

[0050] With the above configuration, the piston-connecting rod mechanism 15 serves as the power transmission mechanism of this system. When the motor 13 is turned on, it drives the transmission wheel 152-AA to rotate. When the transmission wheel 152-AA rotates under force, it drives the crank 152 to rotate via the fixed shaft 152-A, which in turn drives the connecting rod 151 located between the cranks 152 to rotate along the fixed shaft 152-A. The other end of the connecting rod 151 drives the discharge rod 5 to reciprocate in the discharge cylinder 12 via the U-shaped connecting end 52, so that the discharge rod 5 can drive the corn in the storage trough 51 above it to extend out of the discharge cylinder 12 for corn sowing, achieving quantitative and fixed-distance corn sowing. Furthermore, the bearing between the shaft of the connecting rod 151 and the crank 152 is used to reduce the friction between the two parts.

[0051] In the above technical solution, the piston connecting rod mechanism 15 provided on the bracket 1 can be configured as follows:

[0052] The piston connecting rod mechanism 15 has fixed supports 153 symmetrically arranged on both sides. One side of the fixed support 153 is connected to the bracket 1 through a horizontal connecting rod 16, and the other side of the fixed support 153 is fixedly connected to the feeding box 2. The fixed rotating shaft 152-A is rotatably connected between the corresponding fixed supports 153 through bearings.

[0053] Through the above-mentioned configuration, the fixed support 153 is connected to the feeding box 2, and the structure is connected to the bracket 1 via the horizontal connecting rod 16. This ensures the structural stability between the feeding box 2, the fixed support 153, and the bracket 1, so that when the device moves on a rough dirt road, it can withstand the impact of uneven ground. At the same time, the bearing is used to reduce the friction between the fixed shaft 152-A and the fixed support 153 when they rotate, thereby enhancing the durability of the device.

[0054] In the above technical solution, the piston connecting rod mechanism 15 and the motor 13 can be connected by transmission in the following manner:

[0055] A large rotating wheel 131 is provided on the end of the motor shaft, and the large rotating wheel 131 and the transmission wheel 152-AA are connected by a belt 17.

[0056] With the above configuration, the large rotating wheel 131 on the motor 13 serves as the power input end of this device. It can drive the transmission wheel 152-AA to rotate via the belt 17, thereby driving the piston connecting rod mechanism 15 to operate, and thus driving the device to start the timed and quantitative sowing of corn.

[0057] In the above technical solution, the discharge cylinder 12 is provided with a groove 122 along its length direction, and the discharge rod 5 is provided with a sliding end 53 corresponding to the groove 122, and the sliding end 53 is placed in the groove 122.

[0058] The above settings ensure that the discharge rod 5 can reciprocate up and down in the chute 122 stably through the sliding end 53 without deflection.

[0059] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
